4.5 Analogue function
• The unit provides an analogue signal that is proportional to the volumetric flow
quantity and the medium temperature�
• The analogue signal can be provided as current or voltage signal�
• Within the measuring range the analogue signal is 4���20 mA (current output) or
0���10 V (voltage output)�
• If the measured value is outside the measuring range or in the event of an
internal error, the current or voltage signals indicated in Figure 1 are provided�
• The measuring range is scalable:
[ASP2] determines at which measured value the output signal is 4 mA or 0 V�
[AEP2] determines at which measured value the output signal is 20 mA or 10 V�
Minimum distance between [ASP2] and [AEP2] = 20 % of the final value
of the measuring range�
MAW
